1. When installing bilateral guardrail nets, it is necessary to accurately grasp the information of various facilities, especially the accurate locations of various pipelines buried in the roadbed. No damage to underground facilities is allowed during the construction process.
2. When the guardrail column is driven too deep, the column must not be pulled out for correction. The foundation must be re-consolidated before driving in, or the position of the column must be adjusted. When approaching depth during construction, attention should be paid to controlling the hammering intensity.
3. If a flange is to be installed on a highway bridge, pay attention to the positioning of the flange and the control of the top elevation of the column.
4. If the bilateral guardrail net is used as a protective fence, the appearance quality of the product depends on the construction process. During the construction, attention should be paid to the combination of construction preparation and pile driver, constantly summing up experience, and strengthening construction management, so that the installation quality of the isolation fence can be improved.
